VEHICLE-TIRE.

SI-ECIFICATION forming part of Letters Patent No. 689,852, datedDecember 31, 1901.

Application filed August 27, 1900. Serial No. 28,123- (No model.

To all whom) it may concern:

Be it known that I, JOHN W. D. CARSLAW,

a subject of the Queen of'Great Britain, and a resident of Chicago, inthe county of Cook and State of Illinois, have invented certain new anduseful Improvements in Tires for Vehicles; and I do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention relates to improvements in cushion-tires for vehicles, andrelates more particularly to means for securing a resilient tire to thewheel-rim, the object being to provide a cheap and effectiveconstruction having much greater durability than other constructions,inasmuch as the fastening devices cannot tear out, as has frequentlyoccurred in other forms.

The invention consists in the matters hereinafter described, and morefully pointed outand defined in the appended claim.

In the drawings, Figure 1 is a cross-section of a tire embodying myinvention. Fig. 2 is a similar cross-section illustrating the positionof the shoulders on the cushion-strip before compression. Fig. 3 is afragmentary side elevation'of a tire embodying my invention. Figs. 4 and5 are sections similar to Fig. 1 and illustrating modified forms-of theclamping-band.

As shown in said drawings, A indicates the rim of the wheel. A indicatesa channel-iron strip secured circumferentially on said rim in anydesired manner and adapted to engage between the side flanges of thesame the cushion-tread B, of rubber or other suitable material.

b 1) indicate shoulders on each side of the cushion-strip B, whichbefore the compression of the tire within the channel-strip extendsomewhat above the flanges of the channel-strip. O O 0 indicate,respectively, clamping-bands, preferably metallic, which engage saidcushion-strip on said shoulders and are drawn tightly around the wheel,thereby compressing the inner portion of the cushion-strip, as indicatedin Figs.- 1, 4, and 5, and acting to retain the cushion-strip withinsaid channel. The said cushion-strip may be of any desired form orshape. The inner side, however, is preferably formed to fit closelybetween the flanges of the channelstrip,with the shoulders on each sideextending somewhat above the same and at their tops, as shown, formingflat contact-surfaces at right angles with the radius of the wheel. Theclamping-bands may also be of any preferred form; but preferably. eachconsists of a wire or metallic band rounded on its inner side to preventcuttingv the cushion at the angle formed by the shoulder. Fig. 1 showssaid band or wire as oval in cross-section. Fig. 4 shows the same as acylindric wire, while Fig. 5 illustrates the same as a semicylindricband,*having its flat side turned downwardly for contact with the flatcontactsurface of the shoulder. Said clampingbands may be put on in anydesired manner to secure the desired compression of the resilient strip.Usually, however, the cushionstrip is placed in the channel-strip, asshown in Fig. 2, and the clamping bands or wires are placed around andin engagement each with a shoulder and on each side of thecushion-strip, thereby compressing the rubber to such an extent that theinner surface of the wire or band lies below the outer edge of theflange of the channel-strip on that side of the tire. The ends of saidclamping-bands are then united by brazing, electric welding, or anyothersuitable or preferred means. Obviously when said strip is thussecured the radial compression of the rubber serves to press the sameoutwardly, completely filling the channel-strips, asindicated in Figs.1, i, and 5,thereby securing efiective binding contact of the sametherewith. At the same 0 time, inasmuch as the inner surface of theclamping-bands falls below the periphery of the flanges, theclamping-bands cannot by any possibility slip over said flanges.

I claim as my invention A tire for vehicle-wheels comprising a channeledstrip adapted to be secured circumfer= entially to the rim, a resilientstrip of rubber or the like fitting closely within the channel andprovided on each side with a groove form= loo ing a fiat-topped shoulderextending around the tire the flat upper surface thereof being locatednormally above the side flanges of I the tire by compressing the rubberbelow the 10 the channel-strip, an annular clamping-band I tops of theflanges. ovalin cross-section and of less diameter than In testimonywhereof I have hereunto subthe flanges of the channel-strip engagingeach scribed my name in the presence of two sub- 5 of said shoulders andacting to compress the scribing witnesses.
